Artist Enrique Chiu led part of the mural effort along the border wall between California and Mexico. He told KPBS in San Diego that if Trump’s administration builds more miles of wall, “it’s more canvas for us.”

Along the far western edge of the border at Playas de Tijuana, Mexico, the barrier extends into the Pacific Ocean.

The 18-foot steel fence stretches 300 feet into the water and was approved in 2011, according to the Los Angeles Times.

A U.S. Border Patrol vehicle waits for undocumented immigrants at a fence opening near the U.S.-Mexico border on Jan. 5 near McAllen, Texas.

“Because of the way the structure in these gaps, the traffic is funneled through these gaps opening right now, and they’re heavily patrolled,” Los Indios Mayor Rick Cavasos told KRGV. Cavasos is a former Border Patrol agent supervisor, the TV station reported.

But others aren’t so sure of the gaps’ effectiveness. One homeowner who lives near a gap told KRGV that he was startled once by the sight of “six kids” walking across the border.
